Adtran introduced a new generation of Terabit-class edge routers with 400G interfaces, targeting rising capacity demands across access, aggregation, and mobile backhaul networks. The announcement reflects a broader shift as 100G becomes standard at the edge, forcing operators to rethink how they scale bandwidth without relying on oversized core routing platforms. Adtran positions the new systems as a compact, energy-efficient alternative designed for deployment in space- and power-constrained environments such as cabinets and central offices.
The new platforms, spanning the FSP 150 and SDX 8000 series, support aggregation from 10G up to 400G in compact form factors. The SDX 8230 targets temperature-hardened outdoor cabinet deployments, while the FSP 150-XG490 addresses higher-density aggregation scenarios. Both platforms run on a unified network operating system that enables automation, simplified provisioning, and operational consistency across deployments. The systems aim to reduce hardware sprawl and streamline inventory by consolidating multiple functions into a single platform.
Adtran also integrates routing with optical transport by combining the new routers with its FSP 3000 IP optical line system and ZR/ZR+ coherent optics. This approach extends 400G transport beyond traditional reach while reducing the need for external transponders. The platforms support advanced services including MPLS, segment routing, EVPN, and IPVPN within an open, disaggregated architecture, alongside unified orchestration tools for end-to-end network control.

“For teams planning their next phase of edge and aggregation upgrades, deploying our new high-capacity edge solutions is as much about practicality as performance,” commented Andy Ruble, GM of access and aggregation at Adtran. “By bringing together compact 400Gbit/s aggregation, integrated optics and unified management, we make it possible to roll out high-capacity routing in tight cabinet and central-office environments while stripping out surplus equipment, cutting footprint sprawl and avoiding increased operational overhead. It’s a more efficient way to build the edge, one that scales smoothly over time, lowers day-to-day operational effort and supports long-term growth, giving operators the confidence to expand on their own terms with a clearer, more sustainable architecture.”
